> Every single Future you look at will look like this,

That's not true. A Future is supposed to schedule itself to be woken up again when it's ready. This Future schedules it to be woken immediately. Most runtimes, like Tokio, will put a Future that acts like this at the end of the run queue, so in practice it's not as egregious. However, it's unquestionably a spin lock, equivalent to back off with thread::yield.
